OSCommerce and LiteSpeed

I have a client who just transferred over to one of my servers and is having trouble with their OSCommerce installation getting stuck on "checkout_shipping.php"

I've Google'd the heck out of it and I've not been able to identify the cause - I know that the old provider was running Apache and we're running LiteSpeed - when I did load this account up on an Apache VPS running the same version of PHP the issue goes away so I'm thinking it may either be a php issue or maybe an issue in the way that LiteSpeed handles the post variables to php... I'm grasping at straws to be honest.

How about register_global?
If it works properly with Apache on the same server, you should compare the phpinfo() output from Apache and LSWS, I think it is a PHP issue.

register_globals is on as well - I'm really leaning towards the issue being with their shipping module but I would appreciate it if you could take a look for me as right now the client is just blaming the issue on LiteSpeed which I'd like to dispell.

What baffles me is that it works fine on their old provider's server running Apache + PHP 5.2.X but not on this LiteSpeed powered server.
